Abstract

The invention relates to a heat dissipation device based on a graphene heating chip. The device comprises a plurality of layers of heat dissipation bodies and graphene heating bodies arranged between every two adjacent layers of heat dissipation bodies, each graphene heating body comprises a heat conduction shell in contact connection with the heat dissipation bodies and a graphene chip fixedly arranged in the heat conduction shell, a contact of each graphene chip is connected with a wire. Through staggered arrangement of the heat dissipation bodies and the graphene heating bodies layer by layer, the heat dissipation area is increased, and the heat conduction effect is improved; heat-conducting sealing layers are arranged on the two sides of each graphene chip to form a first protection layer, and a heat-conducting insulating plate is arranged to form a second protection layer, so that the sealing effect is improved; and the dual safety protection packaging mode of the ceramic adhesive and the high-temperature insulating paint is anti-creeping and safe to use, so that the heat conduction of the two sides of each graphene chip is more uniform, a heating adhesive sheet is not easy to burn out, the effective safety protection of each chip is ensured, and the insulating property is improved.

Description

technical field [0001] The invention relates to the technical field of heat sinks, in particular to the field of encapsulation and application of graphene heating chips, and specifically refers to a heat dissipation device based on graphene heating chips. Background technique [0002] The radiator is an important part in the fields of automobile engine cooling system and household electric heater, etc. Its function is to dissipate the absorbed heat into the air to form heat exchange. Current car radiators and household electric heaters have high power and consume a lot of electricity. Therefore, a radiator with low power and high energy is required to be widely used. The graphene heating chip is energized to convert electrical energy into heat energy, and can meet the requirements of providing high heat with low power. However, the packaging of the heating chip in the existing heat dissipation device has the problems of easy deformation and poor heat dissipation, so that the...
